[Patch v5 1/2] net: ethernet: xilinx: Generate random mac if none found
From: Zubair Lutfullah Kakakhel
Date: Fri Sep 02 2016 - 07:40:40 EST
At the moment, if the emaclite device doesn't find a mac address
from any source, it simply uses 0x0 with a warning printed.
Instead of using a 0x0 mac address, use a randomly generated one.
